Subject: [PATCH v2 0/1] iio: bmi323: have the peripheral consume less power
The bmi323 chip is part of handhelds PCs that are run on battery.
One of said PC is well-known for its short battery life, even in s2idle:
help mitigate that by putting the device in its lowest-consumption
state while the peripheral is unused.
Have runtime-pm suspend callback save used configuration registers
and runtime-pm resume callback restore saved registers to restore
the previous state.
Changelog:
- V2: patch 1:
+ change patch commit message
+ drop removal callbacks and use devm_add_action_or_reset
+ split bmi323_init in two functions
+ separate regs to save and relative value
+ drop unhelpful consts ptr modifiers
+ add a comment to explain why BMI323_FIFO_CTRL_REG is
being used in runtime resume
